WHEN THE IGNITION SW IS TURNED TO ACC POSITION THE CURRENT FROM THE CIG/RADIO FUSE FLOWS TO TERMINAL 1 OF THE
SHIFT LOCK ECU. WHEN THE IGNITION SW IS TURNED TO ON POSITION THE CURRENT FROM THE ECU±IG FUSE FLOWS TO
TERMINAL 3 OF THE ECU.
1. SHIFT LOCK MECHANISM
WITH THE IGNITION SW ON, WHEN A SIGNAL THAT THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) AND A SIGNAL THAT
THE SHIFT LEVER IS PUT IN ªPº POSITION (CONTINUITY BETWEEN P1 AND P OF THE SHIFT LOCK CONTROL SW) IS INPUT TO THE
ECU, THE ECU OPERATES AND CURRENT FLOWS FROM TERMINAL 3 OF THE ECU " TERMINAL SL+ OF THE SHIFT LOCK
SOLENOID " SOLENOID " TERMINAL SL± " TERMINAL 5 OF THE ECU " GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID TO
TURN ON (PLATE STOPPER DISENGAGES) AND THE SHIFT LEVER CAN SHIFT INTO OTHER POSITION THAN THE ªPº POSITION.
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW IN ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN ªPº POSITION (NO CONTINUITY BETWEEN P2
AND P OF SHIFT LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 4 OF THE ECU " KEYINTERLOCK SOLENOID IS
CUT OFF. THIS CAUSES THE KEYINTERLOCK SOLENOID TO TURN OFF (LOCK LEVER DISENGAGES FROM LOCK POSITION) AND
THE IGNITION KEY CAN BE TURNED FROM ACC TO LOCK POSITION.

WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 18 OF THE WIPER AND WASHER SW, TERMINAL 2 OF
THE WASHER MOTOR AND TERMINAL 4 OF THE WIPER MOTOR THROUGH THE WIPER FUSE.
1. LOW SPEED POSITION
WITH WIPER SW TURNED TO LOW POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW "
TERMINAL 7 " TERMINAL 3 OF THE WIPER MOTOR " WIPER MOTOR " TERMINAL 1 " TO GROUND AND CAUSES TO THE WIPER
MOTOR TO RUN AT LOW SPEED.
2. HIGH SPEED POSITION
WITH WIPER SW TURNED TO HIGH POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW "
TERMINAL 13 " TERMINAL 2 OF THE WIPER MOTOR " WIPER MOTOR " TERMINAL 1 " TO GROUND AND CAUSES TO THE WIPER
MOTOR TO RUN AT HIGH SPEED.
3. INT POSITION
WITH WIPER SW TURNED TO INT POSITION, THE RELAY OPERATES AND THE CURRENT WHICH IS CONNECTED BY RELAY
FUNCTION FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW " TERMINAL 16 " TO GROUND. THIS FLOW OF CURRENT
OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW "
TERMINAL 7 " TERMINAL 3 OF THE WIPER MOTOR " TERMINAL 1 " TO GROUND AND THE WIPER FUNCTIONS.
THE INTERMITTENT OPERATION IS CONTROLLED BY A CONDENSER'S CHARGED AND DISCHARGED FUNCTION INSTALLED IN
RELAY AND THE INTERMITTENT TIME IS CONTROLLED BY A TIME CONTROL SW TO CHANGE THE CHARGING TIME OF THE
CONDENSER.
4. WASHER CONTINUOUS OPERATION
WITH WASHER SW TURNED TO ON, THE CURRENT FLOWS FROM TERMINAL 2 OF THE WASHER MOTOR " TERMINAL 1 "
TERMINAL 8 OF THE WIPER AND WASHER SW " TERMINAL 16 " TO GROUND AND CAUSES TO THE WASHER MOTOR TO RUN AND
WINDOW WASHER TO JET. THIS CAUSES THE CURRENT TO FLOW TO WASHER CONTINUOUS OPERATION CIRCUIT IN TERMINAL 18
OF THE WIPER AND WASHER SW " TERMINAL 7 " TERMINAL 3 OF THE WIPER MOTOR " TERMINAL 1 " TO GROUND AND THE
WIPER FUNCTION.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF WASHER MOTOR, TERMINAL 4 OF REAR WIPER
RELAY AND TERMINAL 1 OF REAR WIPER MOTOR THROUGH THE WIPER FUSE.
1. REAR WIPER NORMAL OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 4
OF REAR WIPER RELAY FLOWS TO TERMINAL 6 OF RELAY " TERMINAL 1 OF REAR WIPER AND WASHER SW " TERMINAL 16 "
TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 4 OF RELAY FLOWS TO TERMINAL 1 "
TERMINAL 4 OF REAR WIPER MOTOR " MOTOR " TERMINAL 2 " TO GROUND AND CAUSES THE MOTOR TO OPERATE THE
WIPER.
2. REAR WIPER INTERMITTENT OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED TO INT POSITION, THE CURRENT FLOWING TO
TERMINAL 4 OF REAR WIPER RELAY FLOWS TO TERMINAL 3 OF RELAY " TERMINAL 10 OF WIPER SW " TERMINAL 16 " TO
GROUND. AS A RESULT, THE RELAY OPERATES AND CURRENT FLOWS FROM TERMINAL 4 OF RELAY " TERMINAL 1 " TERMINAL
4 OF REAR WIPER MOTOR " MOTOR " TERMINAL 2 " TO GROUND, CAUSING THE MOTOR TO ROTATE TO OPERATE THE WIPER.
AT THIS TIME THE CONTACT IN THE WIPER MOTOR CLOSED AND THE CURRENT FLOWS FROM TERMINAL 1 OF REAR WIPER
MOTOR " TERMINAL 3 " TERMINAL 2 OF REAR WIPER RELAY " TERMINAL 1 " TERMINAL 4 OF REAR WIPER MOTOR "
TERMINAL 2 " TO GROUND.
THUS, THE INTERMITTENT±STOP CIRCUIT OPERATES, THE CONDENOR IN THE CIRCUIT CHARGES AND THE WIPER CONTINUES TO
OPERATE UNTIL REACHING THE STOP POSITION. AFTER THE WIPER STOPS, CURRENT DOES NOT FLOW TO THE
INTERMITTENT±STOP CIRCUIT FROM TERMINAL 2 OF RELAY, BUT THE CONDENSER DISCHARGES CURRENT INTO THE
INTERMITTENT CIRCUIT AND THE CIRCUIT OPERATES UNTIL THE CONDENSER DISCHARGE ENDS. AS A RESULT, THIS DISCHARGE
INTERVAL BECOMES THE INTERMITTENT TIME.
WHEN THE CURRENT IS DISCHARGED COMPLETELY, THE CURRENT FLOWING TO TERMINAL 4 OF RELAY FLOWS TO TERMINAL 3
" TERMINAL 10 OF REAR WIPER AND WASHER SW " TERMINAL 16 " TO GROUND.
THEN, THE CURRENT IN TERMINAL 4 OF RELAY FLOWS FROM TERMINAL 1 " TERMINAL 4 OF MOTOR " MOTOR " TERMINAL 2 "
TO GROUND AND ROTATES THE MOTOR. THROUGH REPEITION OF THIS PROCESS, INTERMITTENT OPERATION OF THE REAR
WIPER OCCURS.
3. WASHER OPERATION
WITH THE IGNITION SW ON AND THE REAR WIPER AND WASHER SW IS TURNED STRONGLY (WASHER SW ON), CURRENT FLOWS
FROM TERMINAL 2 OF WASHER MOTOR " TERMINAL 3 " TERMINAL 2 OF REAR WIPER AND WASHER SW " TERMINAL 16 " TO
GROUND SO THAT THE WASHER MOTOR ROTATES AND WINDOW WASHER EJECTS THE SPRAY, ONLY THE WHILE THE REAR
WASHER SW IS TURNED, WHEN THE REAR WIPER SW IS OFF, AND THE REAR WIPER AND WASHER SW IS THEN TURNED IN THE
OFF DIRECTION, WASHER LIQUID WILL ALSO SPLAY.
